If your host is already programmed to display pictures using Accuterm escape sequences, you may not have to change the host programming at all. Just mount the network drive containing your pictures on your Mac using the Finder's Go Menu. (See "MOUNTING A WINDOWS PC DRIVE TO ACCESS YOUR PICTURES").
OR
You can display pictures from the web with MacWise version 12.4.4 or later.

Height and width are optional; if specified (and not zero), the image is scaled to "height" rows and "width" columns. Otherwise, the original image size is used.

If aspect is non- zero, the image aspect ratio is preserved (the specified width or height is reduced to preserve the aspect ratio).

Border is
N for no border,
B for simple border,
R for raised border or
I for inset border style.

Note: MacWise only supports the B (simple) border.

Images are considered “protected” data.
A “clear un-protected characters” command will not clear images from the terminal
screen.

WEB FILE NAMESMacWise will get the picture from the web if the address begins with http
For instance, a valid filename would be http://www.macwise.com/MacWise-Screen.jpg
(Requires MacWise version 12.4.4 or later).

PC FILE NAME PATHSTo maintain compatibility with PC's on the network, it is best to use DOS file name paths in your host programming. Then the same programming will work for PC's running Accuterm and Macs running MacWise.

MOUNTING A WINDOWS PC DRIVE TO ACCESS YOUR PICTURES
You can also access a Windows PC over the network to retrieve your pictures.
Click on the Desktop and then select "Connect to Server" from the Go Menu.
Then use an smb path to mount the PC server.
smb://IPAddress
or
smb://PCName:PCPassword@IPAddress/PCDriveName
Then the PC drive "PCDriveName" will be mounted on your Mac Desktop.
When you display a picture from the PC drive on the network, you would use a pathname like this:
Z:\MyPicturefolder\MyPicture.jpg

MAC FILE NAME PATHS
File names must be complete paths.
You can use Mac filename paths such as VolumeName:MyPicturefolder:MyPicture.jpg
(where VolumeName is the name of the drive).
Mac path names use colons to separate folders.
Pictures can be on your Mac or on a network drive.
If you use "BootVolume" as the Volume Name, MacWise will automatically use the name of your Mac drive.
BootVolume:MyPicturefolder:MyPicture.jpg

EXAMPLE:
Basic program to display a picture "MyPicture" using the original size and aspect ratio at row zero and column zero

Note: you must have Kermit enabled under the MacWise Connection Menu to do Kermit file transfers.

For ASCII downloads, MacWise ignores the file path and stores the downloaded file into your Documents folder in a folder called kermit_transfers as file name ft.txt

user/documents/kermit_transfers/ft.txt

ESC STX D p o m ; pathCR

Protocol p may be A (ASCII),

K (Kermit);

Overwrite o may be O (overwrite) or N (no overwrite);

Mode m may be T (text)

or B (binary). Path is the drive, directory and file name of

the file being received. When using Kermit protocol,

only drive and directory need be

specified, as the file name is included in the transfer protocol;

however if the file name is specified here, it overrides the file

name included in the transfer protocol.

Return Status of Last File Transfer

ESC STX S Returns status of last file transfer. Status message is:

Status: s f i l es f bytes bCR

where f is the number of files transferred, b is the number of

bytes transferred, and s is the transfer status:

0 = transfer successful

1 = unable to open file

2 = transfer aborted by operator

3 = file already exists

4 = terminated due to timeout

5 = terminated due to corrupted data

6 = invalid packet type

7 = terminated by remote program

8 = 8 data bits required for protocol

9 = software flow control not allowed for protocol

Downloading File Complete. Stop Download and close file.

ESC STX C X

End capture. The file containing the captured data is closed.

4. Upload a file from Mac to Host as ASCII Text

ESC STX U p m ; path CR
Upload file from Mac to host. Protocol p may be A (ASCII)
Mode m may be T (text)
Path is ignored and assumed to be ~user:Documents:pick

Notes: path must end with a text file having a .txt extension
For instance the following path would work:
C:\AnyFolderName\MyFile.txt
MacWise will look in the User's Documents folder for a folder called pick and a file called MyFile.txt
MacWise automatically creates the pick folder. You just need to drag MyFile.txt to the pick folder
before you start your file transfer.

5. 80/132 Column modes

Select 132 Column Mode (MacWise actually supports 156 columns)

ESC STX E Selects extended (132 column) video mode as defined by the

extended columns and rows in the Screen Settings category

in the Settings dialog box.

Select 80 Column Mode

ESC STX N Selects normal (80 column) video mode as defined by the

normal columns and rows in the Screen Settings category in

the Settings dialog box.

6. Launching a web browser or email

Process URL link for Mail or Web page

ESC STX < URL CR

Launches your browser and goes to the URL provided by the host *
Can also launch files on your Mac

NOTE: If the URL does not contain http or mailto, then MacWise attempts to open a document on your Mac. For instance...
PRINT CHAR(27):CHAR(2):"<":"MyDrive:MyFolder:MyFilename"
or
PRINT CHAR(27):CHAR(2):"<":"MyFilename" (no path is supplied here so the file would need to be in the MacWise folder.

With MacWise 14.0 or later, if you use "BootVolume" as the MyDrive Name, MacWise will automatically use the name of your Mac drive.
PRINT CHAR(27):CHAR(2):"<":"BootVolume:MyFilename"

With MacWise 14.0 or later, if you use "UserDesktop" as the MyDrive Name, MacWise will look for the file on the Desktop.
PRINT CHAR(27):CHAR(2):"<":"UserDesktop:MyFilename"

With MacWise 14.0 or later, you can use DOS file names like this...
PRINT CHAR(27):CHAR(2):"<":"C:\MyFolder:MyFilename"

With MacWise 14.0 or later, slashes are no longer allowed in the file name

NOTE 2: There are no error messages generated if the host has supplied an incorrect command for the URL or file.

ESC CTRL B > URL CR
Same as above

Running a Script from the Host Computer
(MacWise 14.1.5 or later)

To run a script from the host system, send the private AccuTerm command:
ESC STX P script CR
where script is the text of a script to execute. Each script statement is separated by a LF or EM control character, and the entire script is terminated with a CR (carriage return character).

NOTE: MacWise currently only supports the FileExists script as of MacWise version 14.1.5
